There’s something undeniably comforting about the warm glow of a log burner crackling away in a living room or cabin. But behind that cozy atmosphere is a vital system keeping your home safe—the log burner flue kit. Whether you’re a seasoned installer or a first-time buyer in Australia, understanding how flue kits work and how to choose the right one is essential for performance, safety, and longevity.
In this guide, we’re breaking down everything you need to know about flue kits for log burners in the Australian market—from materials to installation tips and everything in between.
What is a Log Burner?
A log burner, also known as a wood-burning stove, is a self-contained heating appliance designed to burn logs or wood pellets. They’re energy-efficient, eco-friendly, and can heat spaces quickly. However, without the right flue system in place, even the best log burner can become inefficient or dangerous.
Why a Quality Flue Kit is Essential
A flue kit is not just an accessory—it’s a must-have. It vents smoke, gases, and particulates safely from your stove to the outdoors. A well-designed flue enhances combustion efficiency, prevents smoke leakage, and reduces the risk of house fires.
Understanding Log Burner Flue Kits
What’s Included in a Flue Kit?
Typically, a log burner flue kit contains:
- Stove pipe
- Ceiling plate
- Flashing (roof or wall)
- Insulated flue pipe
- Fire stop spacers
- Cowl or rain cap
- Fixing brackets
Vertical vs Horizontal Flue Kits
Vertical flues vent through the roof and are more common and effective for drawing smoke upward.
Horizontal flues (through the wall) are sometimes used but can require additional fans or draft boosters in low-pressure areas.
The Role of Stainless Steel in Flue Kits
Durability in Harsh Aussie Weather
Australia’s climate can be brutal—coastal salt, outback heat, and alpine snow. Stainless steel, especially 304 and 316 grades, handles them all without corroding.
Fire Safety and Compliance
Stainless steel flues meet AS/NZS 2918:2018 standards, offering superior resistance to high temperatures and minimizing fire risks.
Components of a Standard Log Burner Flue Kit
Stove Pipe
This is the section that connects your burner to the flue. It’s usually single-wall and made from galvanised or stainless steel.
Flue Pipe
This section carries smoke through your roof or wall. It’s typically double- or triple-insulated.
Flashing, Cowl, and Ceiling Ring
Flashing keeps water out of your roof or wall. A rain cap or cowl prevents downdrafts and animal entry. The ceiling ring ensures a neat interior finish.
Fire Stops and Insulation
These components prevent heat transfer to combustible materials like wood framing and ceiling panels.
Double Wall vs Single Wall Flue Kits
Key Differences
- Single Wall: Less expensive, good for short runs with plenty of clearance.
- Double Wall: Better insulation, requires less clearance, ideal for tighter indoor spaces.
Which One is Right for Your Setup?
If your flue passes near walls or ceilings, double-wall is the safest choice. For freestanding, open installs, single-wall may suffice.
Choosing the Right Flue Kit for Your Log Burner
Size Compatibility
Measure your log burner’s outlet. Most common diameters in Australia are 125mm, 150mm, and 200mm. The flue should match or exceed the burner size to avoid smoke spillage.
Indoor vs Outdoor Installation
Indoor setups require more insulation and compliance with clearance regulations. Outdoor burners have more flexibility but still need caps and braces for wind.
Through-Roof or Through-Wall Systems
Through-roof systems are easier to maintain draft but may involve roof penetrations.
Through-wall systems need thimbles and insulation to protect external walls.
Australian Standards and Compliance
AS/NZS 2918:2018 Overview
This standard regulates installation, materials, and safety of solid fuel appliances in Australia. All components must be tested and certified to comply.
Clearances and Safety Codes
A minimum clearance of 100mm–150mm is required from the flue to combustible materials unless otherwise specified for insulated kits.
How to Install a Log Burner Flue Kit
DIY Installation Tips
- Read the manufacturer’s instructions thoroughly.
- Always wear protective gloves when handling stainless steel.
- Use a laser level or plumb bob for vertical accuracy.
Hiring a Certified Installer
If you’re unsure, it’s best to go pro. Certified installers ensure your system meets fire regulations and performs efficiently.
Step-by-Step Installation Overview
- Choose your flue route (roof or wall)
- Assemble pipe sections from stove upward
- Cut and prepare the roof or wall penetration
- Install flashing, fire stops, and ceiling plates
- Secure and test for smoke leaks
Draft and Airflow Management
Importance of Correct Draft
Good draft pulls smoke up and out. Poor draft causes smoke spillage and increased creosote.
Dampers and Air Controls
Install a flue damper to control airflow and maintain optimal combustion.
Cleaning and Maintenance
How Often to Clean Your Flue
Inspect your flue every 2–3 months during heavy use. Clean at least once a year to remove soot and creosote.
Signs of Creosote Build-Up
- Black, tar-like residue inside the pipe
- Reduced draft
- Smoky smell indoors
Tools and Techniques for Safe Cleaning
Use a chimney brush, soot vacuum, or hire a professional chimney sweep.
Common Issues and Troubleshooting
Smoke Backflow
Caused by poor draft, a blocked flue, or wind direction. Solutions include raising the flue height or installing a cowl.
Leaks and Rust
Usually a sign of poor flashing or cheap materials. Upgrade to stainless steel for long-term performance.
Cold Drafts
Insulate the flue or add a draft stopper when the stove isn’t in use.
